Description
Technical field
This utility model relates to a kind of salvaging bit tool.
Background technology
At present, in some engineerings of waterpower water power, when particularly rig works in groove, when cannot normally work in drill bit thereon is easily falling into groove, generally require an instrument that can salvage drill bit of looking for, and preferably drill bit can not be made again to drop or turn on one's side during salvaging；In consideration of it, invented content of the present utility model.
Utility model content
This utility model purpose there are provided a kind of salvaging bit tool, this utility model has simple structure, easy to make, and drill bit can be kept during carrying on a steel cord not tilt rollover and be stuck in groove internal face or again drop, it is adaptable to waterpower water power cut-pff wall grooving engineering.
In order to achieve the above object, the technical solution of the utility model is:
A kind of salvaging bit tool, including a left side three claw with three calvus and the right side three claw with three calvus；The upper end of a left side three claw of described three calvus of band and the right side three claw with three calvus is movably connected with front shoe, rear fixed plate by the first pin；The second pin of fixing steel wire rope it is also equipped with between described front shoe and rear fixed plate；Three calvus bottom weldings of a left side three claw of described three calvus of band are provided with the first arc clamp, and three calvus bottom weldings of the right side three claw of described three calvus of band are provided with the second arc clamp；The first described arc clamp and the second arc clamp enclose the Outside Dimensions salvaging ring on a size of drill bit in fencing up；Be provided with between a left side three claw and the right side three claw with three calvus of described three calvus of band can make the first arc clamp, the second arc clamp fence up just block salvage ring spring；And the first arc clamp, the second arc clamp distance of separation strut more than drill bit width when being also equipped with supporting on a left side three claw of described three calvus of band or the right side three claw with three calvus, can be made.
The beneficial effects of the utility model are: a kind of salvaging bit tool of the present utility model, there is simple structure, easy to make, and drill bit can be kept during carrying on a steel cord not tilt rollover and be stuck in groove internal face or again drop, it is adaptable to waterpower water power cut-pff wall grooving engineering.

Detailed description of the invention
Embodiment 1
A kind of bit tool of salvaging of the present embodiment, as shown in Figure 1, 2, including a left side three claw 1 with three calvus and the right side three claw 2 with three calvus；The upper end of a left side three claw 1 of described three calvus of band and the right side three claw 2 with three calvus is movably connected with front shoe 4, rear fixed plate 5 by the first pin 3；The second pin 6 of fixing steel wire rope it is also equipped with between described front shoe 4 and rear fixed plate 5；Three calvus bottom weldings of a left side three claw 1 of described three calvus of band are provided with the first arc clamp 7, and three calvus bottom weldings of the right side three claw 2 of described three calvus of band are provided with the second arc clamp 8；The first described arc clamp 7 encloses size with the second arc clamp 8 in fencing up (the i.e. first arc clamp 7 contacts with the second arc clamp 8 and salvages the Outside Dimensions (i.e. salvaging the outer perimeter of ring) of ring on a length of drill bit of the inner circumferential after surrounding ellipse or circle；Be provided with between a left side three claw 1 and the right side three claw 2 with three calvus of described three calvus of band can make first arc clamp the 7, second arc clamp 8 fence up just block salvage ring spring 9；And first arc clamp the 7, second arc clamp 8 distance of separation strut 10 more than drill bit width when being also equipped with supporting on a left side three claw 1 of described three calvus of band or the right side three claw 2 with three calvus, can be made.
When drill bit is because of wire cable rupture, and when being in vertical position in groove, a kind of salvaging bit tool using the present embodiment is the simplest and convenient；First spring 9 will be utilized to have fenced up and first arc clamp the 7, second arc clamp 8 of compact joint pulls open, utilize strut 10 on wherein a left side three claw 1 with three calvus or the right side three claw 2 with three calvus across between a left side three claw 1 with three calvus, the right side three claw 2 with three calvus, thoroughly strut a left side three claw 1 with three calvus and the right side three claw 2 with three calvus, and make distance between the two more than drill bit width；Then when fishing, when the salvaging bit tool of the present embodiment is under the drive of steel wire rope, increasingly send in groove, when the suspension ring of drill end in mud in groove encountered by strut 10, strut 10 can be backed down, a left side three claw 1 with three calvus, the right side three claw 2 resilience under the action of the spring with three calvus, make first arc clamp the 7, second arc clamp 8 just block salvaging ring, thus implement to salvage.
The a kind of of the present embodiment salvages bit tool, has simple structure, easy to make, and drill bit can be kept not tilt rollover and be stuck in groove internal face or again drop during carrying on a steel cord, it is adaptable to waterpower water power cut-pff wall grooving engineering.
